I had a hard time solving the org.hibernate.type.descriptor.java.EnumJavaTypeDescriptor.fromOrdinal(EnumJavaTypeDescriptor.java:76)error that I got while reading the value from the database.
While using the Spring Boot application, I saved some values in the database as an INT that I had to map back with the enum UserRole. The challenge: I used id and name in the enum, but instead of starting the id value from 0, I started the ID value from 1.
Problem Statement:
I have installed RabbitMQ on windows machine N number of times, but this time, it swallowed all my brain. Reason? Maybe the new permissions/policies that my company has enforced. I have installed Erlang 10, set ERLANG_HOME as well, and then installed RabbitMQ 3.7.7. No error, no exception, but I was unable to see RabbitMQ as a service.
There are multiple ways of storing information on an instance, like EBS or EFS. EBS is Elastic Block Storage and can be considered as if you have a high capacity Storage Device attached to your computer. Whereas EFS is Elastic File Storage and can be considered as if you have attached an external storage device attached to your computer. It may depend on your application or use case you choose to use what among both, but for our case, that we are discussing today, we are going to use encrypted EFS with EC2 Linux instance.
Let's create EFS using CloudFormation. You can use the following template to create the resource. Just pass the appropriate values when asked while creating the resource.

In AWS, one of the common challenges that we all of us face is how to send custom application stats to CloudWatch for monitoring like we send memory, CPU, and I/O stats for automatic monitoring. I did this in one of my recent projects, and I want to share that with all of you through this article.
This approach works fine for:
